46. Research in Motion

RIM, founded in 1984, has been fighting to maintain market share while losing customers to Apple’s iPhone and to phones that use Google’s Android operating system, but the BlackBerry brand is still powerful among corporate users. More recently, sales have been slow for its PlayBook, a tablet whose brand proposition and target market has been unclear: business people or consumers. CMO Keith Pardy announced his resignation in February, weeks before RIM released the PlayBook; no replacement has been named. RIM says that early next year, it will introduce software upgrades for the PlayBook and a higher-powered BlackBerry, to run on the new QNX operating system.
